Polar Coordinates

Polar Coordinates are another way to express where a point in space is in relation to another. Polar Coordinates work much in the same way you might give someone directions to your house. You would give someone a direction to go and then how far they should travel in that direction. The same would be true if you have ever done a compass course. See the example below on giving directions from Riley to Notre Dame.
